McCarthy revealed that he had been giving Fyvie advice since his arrival and tipped the young Scot to become a real asset for the Latics.

He told the club's official website: "I had to wait six months to get a chance and coming down from Scotland was a bit tough for me because I was moving away from home, but I've come in and settled really well and I love it here.

"I've said to Fraser already just to take his time and he knows it will take time.

"He's a good lad and after meeting him for the first time he seems like the sort of person who will settle in really well here.

"He's done well with us today but once he's training with us more he'll really kick on.

"I've always thought he is a great talent and obviously I'm delighted that he is here and I'm sure he'll come in and do well because he's looking sharp in training - Aberdeen started a couple of weeks earlier than us so he has got that little bit extra coming in and he's looking really good."

McCarthy also welcomed the competition that Fyvie's arrival will bring to the Wigan midfielder, saying that it can only benefit manager Roberto Martinez and the club.

"It's always good to have competition in the position you play in because it makes you push yourself and keeps you on your toes," he added.

"It isn't easy to get a place in the team and you need to work really hard in training, which is something I'm happy to do because I always want to give it my best shot.

"Obviously, it's down to the gaffer to pick the players but it is also down to us because we have to show that we want to be there and make it difficult for the gaffer to choose between us."
